in tsmc 0.35, I have designed an op amp with dual supplies of +/-2.5V with bulk/substrates connected to vss(-2.5V). Meanwhile, I designed a comparator which uses a single supply of +5V/0V with bulk connected to GND. When I connected the output of the opamp to the comparator's input, the output of the comparator is pretty bad. Is it because the bulk/substrate are shorted with different voltages? (-2.5V and GND 0V?) What are other solutions???
Because I need an output of 5V and 0V. Thank you!!!! Hoped for your immediate reply.
